Abstract
The value of assessing health-related quality of life (HRQoL) in traumatic brain injury (TBI) patients has been increasingly recognized in recent years. Yet, research examining generic and TBI-specific quality of life (QOL) methodologies within this population has been limited, rendering decisions to use one alternative over another difficult and based largely on conceptual grounds. The current study compared widely used generic QoL/HRQOL measures (Satisfaction With Life Scale, 36-item Short Form Survey) and newer population-specific HRQoL measures (Quality of Life after Brain Injury [QOLIBRI], Trauma-Quality of Life [TQoL]) among 77 TBI and 23 orthopedically injured trauma control patients. The QOLIBRI Cognition and Physical Problems subscales were the only HRQoL scores across the four instruments administered that differentiated between patient groups: participants with TBI reported being significantly less satisfied with their cognitive abilities and more bothered by physical problems. Analyses of the unique population-specific QOLIBRI content revealed that 12.2-31.5% of TBI patients endorsed dissatisfaction and 28.8-51.4% endorsed being bothered by items unique to the QOLIBRI. Endorsement rates for unique TQoL items ranged from 1.4-75.7%. Overall, the QOLIBRI and TQoL appear to capture important information pertinent to patients with TBI and trauma. Inclusion of these disease-specific HRQoL measures is recommended over the use of only generic measures among TBI populations.
